Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom is a strength to the wise man more than ten rulers that are in a city. 20 Surely there is not a righteous man upon earth that does good, and sins not.
21 Also do not take heed to all words that are spoken, lest thou hear thy servant curse thee. 22 For many times also thine own heart knows that thou thyself likewise have cursed others.
